The Subarray Sums Divisible by K approach is a technique used to solve problems that involve finding the number of subarrays in an array whose sum is divisible by a given number (K). The approach uses the concept of “prefix sums” and “modulo operation” to efficiently find the number of such subarrays in linear time […]

In C++, input and output (I/O) operations are performed using the standard input/output library, which is defined in the <iostream> header file. The basic I/O operations in C++ are performed using the following four standard streams: Here’s an example of a simple program that uses cin and cout to read an integer from the keyboard

What is amortised time complexity and method to calculate? Amortized time complexity is a measure of the efficiency of an algorithm that takes into account the average time taken by the algorithm over a sequence of operations, rather than just the worst-case or best-case time complexity. One method for calculating the amortized time complexity of
